Fabric Server from a Fabric Pack

Making a Fabric Server from A Fabric

Making a server is easy. Whether in Linux or Windows.

Create a folder somewhere that will be the server folder.

Open the pack folder.

Select everything in pack folder.

Now copy that selection. For example right click the selection and choose copy.

Open the server folder you made in step #1.

Paste. for example right click and choose paste.

Download the installer for Fabric. This one installer covers all versions from 1.14.4 to now. The latest installer can always be downloaded from fabricmc.net/use/.

Move this installer jar to the server folder

Open your shell/terminal/cmd/powershell

Enter the server folder you created, you might have to navigate to it in your file manager.

In the following you can replace 1.16.5 with whatever version of Minecraft your Fabric is designed to use. Enter the command java -jar name_of_installer.jar server -mcversion 1.16.5 -downloadMinecraft

A bunch of stuff will happen

At this point the server is created but not debugged

I recommend deleting installer jar as you don’t need it anymore.

Start the server

In your shell get a directory listing of the jars (Linux: ls *.jar Windows: dir *.jar)

If you haven’t done so already, delete the installer jar.

There will be a new jar file that doesn’t say installer and starts with “fabric”, this is the file you will be executing, note it down.

From your shell to start the server do java -jar fabric-server-launch.jar

you can add nogui to the end to stop the gui from popping up.

The server will start then stop, telling you edit the eula.txt. so that and set the one value there to true.

Start the server again.

The server has started.

Debug the server (do not run the client here)

The server you created will likely crash because quite a few mods are not server friendly or coded in such a way that they will try to load client side classes on a server. When it happens there will be a crash report. Open the file and look at the top trace block to see what crashed.

Check to see if there is an update for the mod, if yes, update it on both the server and the client, rerun the server

If the server crashes again on the same mod, try a lower version, make sure the client matches

If it crashes again, remove the mod from both the server and the client

Eventually you’ll have a running server and client that should connect to it

Debug the client

Great job on creating a functioning server

now run the client that was adjusted alongside the server

if it crashes look at the crash report and either update, rollback or remove the mod from the client and on the server if it exists

eventually you’ll have a running client

Final Steps

start the server

start the client

enter multiplayer button on client

click on direct connect

enter the ip address of the server and hit connect

in a short few moments you should now be connected to your server

Where to go from here

You can export the pack using one of the launcher talked about on my kreezcraft.com/info/modded-minecraft-pack-launchers/ page, or you could use the export to publish the pack at www.curseforge.com/minecraft/modpacks/ and if it is the latter I recommend you follow this article kreezcraft.com/packs-dev/how-to-make-a-forge-server-from-a-forge-pack/publish-a-server-pack/ too.
